Hi, we have Samsung Android tablets in kiosk mode and are trying to let users share an image from the Gallery app through the native Messages app. After adding some blocked packages to the kiosk background apps list, the app opens a bit further, but sending still fails with the message: “This app isn’t allowed by the device owner.”
The same device also showed access denied behavior when opening some default apps from kiosk. We tried disabling kiosk mode temporarily, but the Messages error still appeared. What policy setting controls this?
